It appears that the user under which you are attempting all this,
doesn't have permission to manage, or otherwise manipulate/view the
printer facilities. My suggestion would be to (if available) go to
http://localhost:631/admin in your browser, and login with the root
password, and then GRANT permission(s) to the user you want to give
access to.

Also insure that the cups user/group were added correctly.

Best wishes.
